Here, the detector 22 is configured to detect the occurrence of an abnormality with respect to its own antenna, and the beacon signal receiver 26 is configured to detect the occurrence of an abnormality for an antenna installed nearby, so the detection unit 22 and the beacon signal receiver ( 26) may be set as the minimum detection configuration of the state detection module 20 .

On the other hand, the abnormal occurrence determination unit 28 may be provided to analyze the input/output signal detected by the detection unit 22, allocate a beacon signal for abnormal occurrence to an input/output channel that is not currently being used, and propagate, or , the abnormality determination unit 28 may be provided to allocate and propagate a beacon signal to the corresponding channel after temporarily stopping the channel having the highest isolation value of the input/output channel when all of the input/output channels are in use.
